# Excel Fill Custom Series

I am wanting to create a custom fill were the series follows an incremental series based an numbers and alphabet characters (Unit 1A, Unit 1B, Unit 1C,....and so on, then the same repeats but starting with Unit 2A, Unit 2B, Unit 2C.....etc.
It is problably a question that has been answered before but I could not find it searching the past threads.

Any ideas would be highly appreciated

Possible solution

In reply to: Excel Fill Custom Series

Hello Ernesto,

Not sure I understand your requirement. If you need a column to be fill as you wrote, I could suggest this:

A2 = Unit 1
A3 = A2
B2 = 65
B3 = IF(A2=A1,B1+1,65)
C2 = A2&CHAR(B2)
C3 = A3&CHAR(B3)

Then you can recopy line 3 as you want
Where you want "Unit 2" to start. Just overwrite the formula in column A with "Unit 2".

Hope this will help !

Clarifying my question

What I need is to develop the sequence all in one column. Unit is the same as saying Office Number, Unit Number, so the series has to start with a word....

I am working in a building office inventory list where I have to list the unit (office spaces) by their assigned label name that goes by floors (1,2,3,4,...). Each floor has a number of spaces that go by letters (A,B,C,D,E,F,...) so in this way I want the list to go in a sequence by floor and by unit number (letter). As in this example 1A, 1B, 1C, 1D, 1E,....then 2A, 2B, 2C, 2D, 2E,.......then 3A, 3B, 3C, 3D, 3E,...all tha way to 33A, 33B, 33C, 33D, 33E,....

Hope this clarifies my question.
Again, thanks for you kind attention!

Assuming there are 4 units on each floor (just to keep it short):
- A1 through A5: 1,1,1,1,=A1+1
- B1 through B5: A,B,C,D,=B1
- C1: =format(A1;"0")&B1
- Then drag down A5:B5 until you reach 33,D (use copy -handle down right in the selection).
- Then drag down C1 until you're next to 33,D
- Copy>Paste Special>Values after selecting column C
- Delete column A and B.

The formula in C1 is a little bit difficult, but rlavoie gave an excellent example (thanks!). The remainder is rather basic use of Excel.

My result in column A:
1A
1B
1C
1D
2A
2B
2C
2D
3A
3B
3C
3D
4A
4B
4C
4D
5A
5B
5C
5D
6A
6B
6C
6D
7A
7B
7C
7D
8A
8B
8C
8D
9A
9B
9C
9D
10A
10B
10C
10D
11A
11B
11C
11D
etc
